The new series just started in November which might explain the omission from this list but it is off to a great start. The book is using three different version of Thor from three time periods to tell an interconnected story. There's young Thor hanging with Vikings on Earth, modern Thor doing his thing around the Universe, and a grizzled old version of Thor in the far distant future Asgard (where he appears to be the only one left?).
The opening story arc features all three version of Thor coming into contact with a mysterious new enemy who is hunting and killing gods and it's really well done. I recommend adding it to your pull list because this will certainly be near the top of CBR's Best of 2013.
